TEP did not perform a site <br /> visit to verify the size, condition or capacity of the antenna mounts and did not analyze antennas <br /> supporting mounts as part of this structural analysis report. <br /> 8) The following material grades were assumed. <br /> a) Legs: ASTM A53-B-46 <br /> b) Bracing: ASTM A36 <br /> This analysis may be affected if any assumptions are not valid or have been made in error. Tower <br /> Engineering Professionals should be notified to determine the effect on the structural integrity of the <br /> tower <br /> 4)ANALYSIS RESULTS <br /> Table 5-Section Capacity(Summary) <br /> ���06 Elevation(ft) �Omponent Size Crit[cal P�K� BP���K� % Pass/Fai[ <br /> No. Type Element Capacity <br /> Ti 190-180 Leg P2.5x203 2 15.028 i 53.866 j W27_9 4 Pass <br /> ,. -- _' ---._-----' ---_.. __.._._.___ .._.__�.__._. .._._._._....._...._._ ._.__.._ ..__�-_._..___..__.Y___._..._....-----.r . 1 ..__.__........._. � <br /> T2 180-160 Leg P3.Sx.226 � 20 64.569 , 96.872 66.7 Pass <br /> -----____�---__ _. _�. _ :_— = __ _. <br /> T3 160-140 Leg P5x.258 � 50 ; -128.241 � 157.510 81 4 Pass <br /> : __ _. . - - - --------_ __.. __...___,-- _.. __ _ ---- _._�_�. _.. � <br /> T4 140-120 Leg P8x.322 � 74 -202.020 i 330 771 � 61 1 ; Pass ' <br /> T5 120-113.333 Leg � P8x.322 � 98 ! -226.348 330.771 68.4 � Pass � <br /> I_'_'_'_�_; �' 4 <br /> T6 ��3.333- � Leg PSx.322 � 110 3 -250.973 ' 330 771 75.9 � Pass � <br /> 106.667 , <br /> tnxTower Report-version 6.0 4.0 <br />
